Description
Technical field
The present invention relates to a kind of longitudinal variable-thickness cold-forming shapes tandem rolling and connect roller manufacturing process and device thereof, belong to section bar process technology and apparatus field.
Background technology
In recent years, along with the continuous development of human civilization with science and technology, caused the exhaustion and the dilution of world's natural resources, cold-rolled forming section is accepted extensively by people as a kind of environmental protection, energy-conservation New Building Materials.Compare with hot-rolled steel section, it is big to have cross section mechanical property, the moment of inertia, torsional rigidity, is easy to construction, and the node of cold-rolled forming section connects also very convenient, needs a large amount of gusset plates unlike hot-rolled steel section that kind, also unlike pipe node that kind need complicacy connection.In addition, being connected of clod wash purlin and colored contour plate is also fairly simple, can single face constructs, characteristics such as antiseptic property is good.Cold-rolled forming section is widely used in industries such as building, communications and transportation, automobile and tractor manufacturing, machine-building, shipbuilding, electric power.Building industry is the topmost user of cold-rolled forming section, and the developed countries building industry has accounted for 40%～70% of its construction(al)steel with cold-rolled forming section.
At present, cold-rolled forming section all be with standard the equal thickness sheet metal, the band steel under the state of normal temperature, become the cross section shaped steel of different shape through method clod washes such as rolling, punching presses.And since the early 1990s in last century, a kind of new technology---vertically (in rolling or forming process, be vertically) continuously thickening degree plate rolling and be developed as far back as Germany along rolling or forming direction.This sheet material, the designer can be made into along thickness on the rolling direction by customizing the continually varying plate in advance according to the actual loading at each position of sheet material and the carrying situation of distortion and entire product in the post forming processing.Because vertically the thickening degree of thickening degree sheet material is to be formed by the motion that rolling in the manufacture process is taken turns continuously; Therefore vertically continuously the increase of the varied in thickness number of times of thickening degree sheet material is to advantages such as cost can not have any impact, and is widely used in industries such as automobile, machinery, building.Vertically thickening degree sheet material has remarkable advantages at aspects such as weight loss effect, mechanical performance, adaptability, thickness optimization distribution, sectional curve variation, following process reliabilities continuously.Research shows, is reference with the equal thickness beam, and the vertically continuous thickening degree board making of utilization becomes the beam of same performance; Its weight minimizing reaches 40%; This also means has saved 40% material, the social environment that lacks day by day for present resource, visible its economic benefit considerable.
At present, it all is to be raw material with equal thickness sheet metal, band steel that cold-rolled forming section is shaped, and its former also can only be applicable to the equal thickness sheet metal, be with steel; Shaping dies is flexible poor, can not utilize metal material fully, and product quality is heavy; Production efficiency is low, and use cost is also higher.Simultaneously, the guiding mechanism of depressing that is used to adjust the patrix position also is to adopt manual adjustments, wastes time and energy during adjusting, can't satisfy the production model of present multiple batches of small lot.Like Chinese patent publication number 101773953A, open day on 07 14th, 2010, the name of innovation and creation was called a kind of roll forming technology and production line of producing broad width U-shaped channel steel; This application case discloses a plate through some dress roller arrangements; The dress roller arrangement bends the plate both sides, makes the plate both sides produce bending angle, and by the direction of motion of plate after the dress roller arrangement make bending angle increase gradually; Until 90 °, make preliminarily forming U type channel-section steel.With existing roll forming technological principle, apply on the roll forming of U type channel-section steel in the method, have certain advance; But the shaping dies of the method production line is flexible poor, only is applicable to the rolling of equal thickness plate, can not utilize metal material fully; And mould therefor is a fixed mould, when needs processing different size, needs to change different dies; And the mechanism for axial adjusting of its roll shaft is used manual adjustment more, and efficient is very low, and use cost is also higher.
Summary of the invention
The present invention is primarily aimed at the defective and the deficiency of prior art, in conjunction with flexible rolling technology and roll forming technology, proposes a kind of longitudinal variable-thickness cold-forming shapes tandem rolling and connects the roller manufacturing process.
The technical scheme of this invention is: with the equal thickness coiled material is raw material; To carry out the thickening degree rolling after get into thickening degree rolling system behind the leveling, pickling in uncoiling; After degreasing, online tempering, become vertically continuous thickening degree sheet material again; Get into the roll forming device and the final section bar that is shaped behind skin pass rolling, the slitting, get into discharge pedestal, subsequent technique also comprises cut-out, tie up and packing etc.
According to said method a kind of cold-forming shapes roll forming device of thickening degree sheet material continuously that is applicable to vertically is provided; It has computer system, checkout gear, discharge pedestal, workbench, workbench and is provided with leveling milling train, slitter and roll forming unit; Sheet material advances and rolling power is provided by power source, imports through decelerator, drive link, shaft coupling transmission and by driving shaft; Vertically thickening degree sheet material gets into the section bar roll forming unit by computer system control after skin pass rolling, cutting continuously, accomplishes the shaping of section bar.
Aforesaid checkout gear; It is made up of pressure sensor, thickness gauge, displacement transducer, velocity sensor etc., need be comprised by the detection system data measured in the roll forming process: tensile force, charging thickness; Roll location, the velocity of rotation of roll etc.Pressure sensor, thickness gauge all are installed in plate import department; Displacement transducer, velocity sensor are installed on leveling milling train and the roll forming unit; Placed accurate sensor in corresponding position, obtained data in real time and be transferred to computer system, computer system is given leveling milling train and roll forming unit transfer of data through calculating again; The breaker roll gap is controlled, and accomplishes the real-time control to leveling milling train and roll forming unit.
The present invention compared with prior art has following outstanding advantage and effect:
1, seamlessly combined flexible rolling technology and roll forming technology; The designer can be made into according to the carrying situation of the actual loading at each position of post forming light plate and distortion and entire product along on the rolling direction by customizing the continually varying plate in advance; And final roll bending formation material; So more can tally with the actual situation, save material;
2, compare with the equal thickness panel products, final products of the present invention are under the situation of equal performance, and weight reduces by 20% to 40%.
3, in process, roll, rectification be control and instant adjusting automatically all, and applicability is wide, precision is high, improved production efficiency and product quality.
Practical function of the present invention is, can realize the production of longitudinal variable-thickness cold-forming shapes, controls die location in real time, automatically, and is easy to adjust, and production efficiency is high, precision is high, material use fully, advantage such as reduce production costs.
